Re: [PLUG] ...nix backup for windows

i had  a backup of windows "system state" files.
(boot files, registry hives, sysvol, etc)
under what circumstances could tar fail to restore a file?
i noticed that most failures were from winnt\system32
which may have "windows file protection".
of course, I attempted to restore to a temp directory

any thoughts?

I'm not sure how Veritas backup works but in general many Windows files are locked while running and can only be backed up with cooperation from Windows. Some commercial products sell separate "system recovery" imaging packages to get around this.

If Veritas backup depends on accessing Windows over SMB or other
mounted volume methods - I don't believe you'll have a reliable
method of backing up these files.

For example, using the open-source "Bacula" Enterprise backup the
Windows client being backed up actually makes a static "snapshot"
volume of the entire disk and then backs up all the files, including the locked
ones. The static snapshot system is called "VSS" in Microsoft terminology, and
currently works on Win2003 server and WinXP clients.

FYI - My recent PLUG talk on Bacula is available at:
